BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as a hybrid tea cut flower Rose plant, and hereinafter referred to by the name ‘FLORI 0102’.

The new Rose plant is a naturally-occurring whole plant mutation of an unnamed proprietary Rosa hybrida selection, not patented. The new Rose plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the mutation parent selection in a controlled greenhouse environment in Mishima, Osaka, Japan in April, 2011.

Asexual reproduction of the new Rose plant by vegetative cuttings in Mishima, Osaka, Japan since August, 2013 has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Rose have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘FLORI 0102’. These characteristics in combination distinguish ‘FLORI 0102’ as a new and distinct Rose plant:

-   -   1. Upright and strong flowering stems.     -   2. Moderately vigorous growth habit.     -   3. Dark green-colored leaves.     -   4. Double-type light purple-colored flowers.     -   5. Excellent postproduction longevity.

Plants of the new Rose differ from plants of the mutation parent primarily in flower color as mutation parent selection have lighter purple-colored flowers.

Plants of the new Rose can be compared to plants of Rosa hybrida ‘FLORI 1301’, disclosed in U.S. Plant patent application Ser. No. 15/330,689. In side-by-side comparisons, plants of the new Rose differ from plants of ‘FLORI 1301’ in the following characteristics:

-   -   1. Plants of the new Rose are taller than plants of ‘FLORI         1301’.     -   2. Leaves of plants of the new Rose are larger than leaves of         plants of ‘FLORI 1301’.     -   3. Stipules of plants of the new Rose are larger and darker         green in color than stipules of plants of ‘FLORI 1301’.     -   4. Flowers of plants of the new Rose are smaller than flowers of         plants of ‘FLORI 1301’.     -   5. Sepals of plants of the new Rose are broader than sepals of         plants of ‘FLORI 1301’.     -   6. Peduncles of plants of the new Rose are shorter than         peduncles of plants of ‘FLORI 1301’.     -   7. Flowers of plants of the new Rose have twice as many stamens         as flowers of plants of ‘FLORI 1301’.

Plants of the new Rose can be compared to plants of Rosa hybrida ‘Ocean Song’, not patented. In side-by-side comparisons, plants of the new Rose differ from plants of ‘Ocean Song’ in the following characteristics:

-   -   1. Flowers of plants of the new Rose are more rounded than and         not as star-shaped as flowers of plants of ‘Ocean Song’.     -   2. Flowers of plants of the new Rose are darker purple in color         than flowers of plants of ‘Ocean Song’.     -   3. Flowers of plants of the new Rose have twice as many stamens         as flowers of plants of ‘Ocean Song’.
